Preparation method of ginsenoside Rg1

InactiveCN101597314ASteroidsOrganic solventSolvent extraction

The invention discloses a preparation method of active principles of ginsenoside Rg1, which is characterized in that total saponins are obtained from different drug ingredients, and the ginsenoside Rg1 with the purity being larger than 90 percent is obtained by a method of organically combining a macroporous absorbent resin method and organic solvent extraction. The preparation method is suitable for industrialized production, can obtain the ginsenoside Rg1 in kilogram and has high extraction yield. Pharmacological tests show that the ginsenoside Rg1 obtained by the preparation method has good drug action.

Highly dispersible granulate for the preparation of formulations of high dosage active substances and procedure for obtaining high dosage active substances thereof

InactiveUS20130108699A1Reduce manufacturing costIncrease chanceBiocideGranular deliveryActive principlePharmacological action

By mixing ibuprofen and a disaggregating agent, the invention involves using these components in a proportion ranging between 96% and 97% by weight for ibuprofen, and between 3% and 4% for the disaggregating agent, which may be Sodium croscarmellose, Crospovidone or Sodium carboxymethyl starch, as well as a mixture thereof. Following the mixing of the raw materials, the mixture is subjected to compaction, granulation and subsequent compression, in order to finally give the tablet a coating; this leads to a significant cost reduction and a significant reduction in the active principle release time, such that the pharmacological action is very fast in time.

Spheroids prepared from an isolated active principle of vegetable origin and a solution of vegetable origin containing the active principle or a precursor thereof

InactiveUS20090123552A1Salicyclic acid active ingredientsBiocideActive principleChemistry

The invention relates to spheroids which are obtained using a method comprising the following steps consisting in: supplying an active principle of vegetable origin in an isolated form; supplying a solution of vegetable origin, containing the active principle or a precursor thereof; supplying an absorbing and adsorbing substance having plastic properties that are compatible with the method; mixing said different products and wetting the mixture with a wetting liquid; extruding the wet mixture; and forming spheroids through the spheronization of the extruded product. The invention also relates to sample applications such as artesunate-based antimalarial spheroids and aspring-based spheroids.
